i can tell you how to farm these ...
Make a mf char and dont do normal den quest
Then level up to level 70+
Then get as much mf gear as possible...
And slay norm corpsefire (the unique zombie in den) without slaying all the monsters in den to leave quest available
Repeat
Good luck! go farm those lvl 1-3 items
P.S. - he drops a "rare" item every time ... good chance of jewel
